Final answer:
For a patient starting hemodialysis with severe hypertension and no diabetes or cardiac issues, an arteriovenous fistula is considered the best type of access due to its lower complication rate, lower infection risk, and better long-term patency.
Step-by-step explanation:
For a patient with severe hypertension requiring hemodialysis but without diabetes or cardiac complications, an arteriovenous (AV) fistula is considered the preferable option for vascular access.
An AV fistula is created by directly connecting an artery to a vein, usually in the arm.
This type of access tends to have fewer complications, a lower risk of infection, and can last longer than other types of dialysis accesses like arteriovenous grafts or central venous catheters. Moreover, an AV fistula typically provides better hemodialysis quality because of higher and more consistent blood flow rates.
